A future interest in real estate created at the time and by the same instrument of the original estate, but limited its immediate authority upon the termination of the prior estate. For example, Hoe Phigg owns a property in fee simple and conveys the property "to Barry Clink and upon Clink's death, to Cora Quibb and her heirs." Cora Quibb has a remainder estate, which is vested because the estate automatically passes to Cora Quibb and her heirs upon the death of Barry Clink.
